Detecting Changes in Ontologies via DAG Comparison

Abstract. Ontologies are shared conceptualizations of a certain domain. As such domains may change, also changes in the ontologies have to be considered, as otherwise there is no way to state which knowledge was valid at an arbitrary point in time. Various ontology version management systems deal with this problem. But often, the differences between two versions of an ontology are not known, thus, it is not possible to incorporate changes into the versioning system. In this paper we present our graph based ontology change detection approach, an evaluation of the prototypic implementation and a comparison to existing change detection systems.
